Mr. Causey explains De Broglie's hypothesis, matter waves and Schrodinger's equation in the development of the wave-mechanical model of the atom. Louis de Broglie proposes the idea that if light can have particle properties then particles should have wave properties. He based his hypothesis on the symmetry of nature and Einstein's formulas from the explanation of the photoelectric effect. In effort to gain support for his idea de Broglie sent his work to Einstein who readily accepted this new hypothesis. However, de Broglie's hypothesis was confirmed until 1927 by Germer and Davison and independently by G.P. Thomson.

Erwin Schrodinger takes the De Broglie Hypothesis and combines it with the Planetary Model to create the Wave Mechanical Model. Schrodinger suggest that the matter wave is a three dimensional standing wave and develops the Schrodinger equation to support it mathematically,

thanks so much for this. Your explanation of De Broglie's matter wave discovery saved my physics paper. You explained it thuroughly and clearly. Much appreciated!!

thank you so much!! you fit an entire lesson into one video and you even introduced a topic that i was later about to study, but thanks to you i get it!

hi, can you please help me with some questions?
here they are:
In what way is the description of the electron using a wave function consistent with de Broglie's hypothesis?
What is meant by the term probability density? Given the wave function, how do we find the probability density at a certain point in space?

Thank you! I learned all the topics for second quarter in just a day! I have a question. Could you produce questionaires for these topics? Please :) I really need your help.

Fantastic explanation. Your method of teaching very inspiring. I am inspired to study physics and Mathematics more. I have always hated these subjects. You are a life saver. Thanks a Million Sir.

How did the Bohr model go by macrophysics?

At low frequency and energy that is true but at high frequency and energy the photon has a very small mass and have particle properties, This is why ultraviolet and x-rays are harmful.

Einstein used this idea to explain the photoelectric effect and won a Nobel Prize for it.

Don't care about wiki.

Your demands for what to know before this lecture is crazy!! Understanding quantum mechanics? Even Feynman didn't understand 😂

wikipedia says that photons have no mass, check wiki's article on photons

Very nice! BUT, Please learn to pronounce these scientists names properly...gives an atmosphere of experience!
de Broglie is pronounced "dee Broy". This was my first of your videos--I subscribed and plan to see the rest.

You sound a bit like a country yokel from England with that accent there.
